Chris Burroughs commented on CASSANDRA-5821:
--------------------------------------------
Ben, since this includes a backport of ConcurrentHashMapV8 as well should we
expect a change in how large (ie # entries) a CLHM can feasible be? I think
Doug Lea's description was that V8 should "more gracefully handles maps that
are huge".
> Test new ConcurrentLinkedHashMap implementation (1.4RC)
